Originally published on NextFuture Should you route your coding API calls through Cursor Composer 2 instead of Claude Sonnet? For engineers and solo operators running code generation through the Anthropic API, the input-token math is clear: $3.00 per million for Claude Sonnet versus $0.50 per million for Cursor Composer 2. Above 10,000 prompts per day, Composer 2 saves $275 per month on input tokens alone. Below 1,000 prompts, migration takes nearly 11 months to pay back. The catch: Composer 2 is a coding-only model — route general reasoning and conversational tasks to Claude Sonnet regardless.…
